BOTTLE-CLOSURE.

T0 all whom t may concern.'

Be it known that I, HARRY M. GRAY, a citizen of the United States, residing at Millvale, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Bottle-Closure, of which the following is a specification.

This invention relates to a closure especially designed for use in connection with bottles. It is the practice, where whiskies and similar drinks are dispensed from bottles, to either replace the corks in the bottles after portions of the drinks have been poured therefrom, or else to utilize a cap for closing each bottle, thus to prevent evaporation and also to prevent dust from entering the bottles.

One of the objects of the present invention is to provide a novel form of closure which can be applied readily to the neck port-ion of a bottle after the cork has been removed and which will close automatically whenever the bottle is placed in an upright position, but will open automatically whenever the bottle is tilted in any direction out of its normal or perpendicular position.

A further object is to provide a structure 0f this character which is simple, durable and inexpensive, can be applied readily, and

will not easily get out of order.

With the foregoing and other objects in view which will appear as the description proceeds7 the invention resides in the combinationand arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a central vertical section through the neck portion of a bottle having the present improvements applied thereto, the closure being shown in its normal or shut position.

Fig. 2 is a view similar to Fig. l, showing the bottle tilted and the closure shifted to open position.

Fig. 3 is' a view similar to Fig. 2 and showing the relative positions of the parts when the bottle is tilted in a plane at rightangles to that in which the bottle is shown tilted in F ig. 2.

Fig. Ll is a plan view of a bottle having the present improvements applied thereto.

Referring to the ligures by characters of reference l designates a tubular body adapted to be inserted into the neck portion of a bottle B so as to lit tightly therein, this body having an annular ange 2 near its upper end designed to rest upon the end of the bottle neck. Extending diametrically through the body l adjacent the center thereof is a pivot pin 3 having spacing sleeves 4s extending to points adjacent the center of the pin, Mounted loosely on the pin 3 and between the spacing sleeves is a stem 5 provided at its lower end with a weight 6 while its upper end, which has a head 7, is extended loosely through an opening S formed in the center of a flat disk 9. The parts are so proportioned that when stem'5 is held vertically by the weight 6, the disk 9, which bears by gravity against the upper end of the body l, will be held concentric with the body so as to completely close the outer end thereof. As stem 6 is loosely mounted on the pin 3 it will be obvious that no matter in what direction the bottle may be tilted out of its normal position, the weight 6 will gravitate toward the wall of the bottle neck and will cause the disk 9 to move upwardly so as to leave an outlet opening 0 between the disk and the lowermost portion of the body l, as shown in Figs. 2 and 3. When the bottle is tilted as shown in Fig. 2, the stem 5 swings in the same vertical plane with the pin 3. When the bottle is tilted as shown in Fig. 3, the stem 5 tilts in a stem intersecting the pin 3. Head 7 prevents the disk 9 from becoming displaced relative to the stem 5 and as the stem is always inclined upwardly and outwardly relative to the tilted body l, it will be seen that the disk 9 tends to gravitate along this inclined stem so as to rest flat t t lll@ disk 9 is free to slide, the stem serving to hold the disk pressed firmly against the open end of the body l While the bottle is tilted, so that the disk thus acts as a means for preventing liquid from leaving the bottle neck in a stream of objectionable size, sometimes occurs when an open bottle is suddenly tilted to a considerable degree.

lWhat is claimed is 1. A bottle closure including a tubular body insertible into the neck or' a bottle, a centrally disposed stem mounted to swing freely in any direction Within the body, a Weight at the lower end of the stem, and a disk loosely mounted upon theupper end portion of the stem and bearing against the end of the body.

2. A closure for bottles, including a tubular body, a Weighted stem mounted to swing freely in any direction Within the body, said stem being normally extended along the longitudinal center of the body, and a disk normally bearing on one end of the body and loosely engaging one end portion of the stem, said disk being slidable upon the end of the body under the action of the stem to open or close the body.

3. A bottle closure including a tubular body insertible into the neck of a bottle, a diametrically disposed pivot in the body, a stem mounted on the pivot at the center or" the body and normally extending along the longitudinal center of the body, spacing means for holding the stem centered in the body, a Weight for holding said stem normally vertical, a closure slidably mounted on one end of the body and loosely engaging the stem, said stem constituting means for holding the closure in centered position when the stem is Vertical.

l. A bottle 'closure including -a tubular body insertible into the neck of a bottle, a diametrically disposed pivot in the body, a stem mounted on the pivot at the center of the body and normally extending along the longitudinal center of the body, spacing means for holding the stem centered in the body, a Weight for holding said stem normally Vertical, a closure slidably mounted on one end of the body and loosely engaging the stern, said stem constituting means for holding the closure in centered position when the stem is Vertical, and means on the stem for holding the closure against remoyal therefrom.

ln testimony that I claim the foregoing as my own, have hereto affixed my signature in the presence of two Witnesses.
